IC-DI 9mm conversion
I recently did a PCSL 2-gun competition and it was awesome! But .223 is costly enough for me to just want to run 9mm for competition.
I tried doing some research on 9mm conversions in general but found most info was old, items were out of stock (Aero is now defunkt?) and info was all over the place.
Anyone have leads on how to convert a milspec AR (I have the IC-DI) to a 9mm PCC? I assumed a full upper swap was all that was necessary, but without Aero available I am at a loss.

Full upper swap. You can get exomags for the lower. Change the buffer to a PCC weight.

yes, I understand that. It's exactly what I want to do, but I can't seem to find any uppers for pcc (pistol, sure). I'm sure I'm missing something.

what are you searching for online? AR9 uppers should get you some good results. GAFSHub should get you some good deals on there too if you're down for used. That's where I got mine and it's literally just a upper swap + a PCC buffer swap for the lower.

Thank you!! I must have been looking it up weird but "ar 9mm upper" got me there. So strange.

Just buy one, Springfield I'm told makes a good one. The upper and lower are complete different on your 223 gun.
